<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qpieseries.html">QPieSeries</a> class presents data in pie charts.</p>
<p>A pie series consists of slices that are defined as <a href="qpieslice.html">QPieSlice</a> objects. The slices can have any values as the <a href="qpieseries.html">QPieSeries</a> object calculates the percentage of a slice compared with the sum of all slices in the series to determine the actual size of the slice in the chart.</p>
<p>Pie size and position on the chart are controlled by using relative values that range from 0.0 to 1.0. These relate to the actual chart rectangle.</p>
<p>By default, the pie is defined as a full pie. A partial pie can be created by setting a starting angle and angle span for the series. A full pie is 360 degrees, where 0 is at 12 a'clock.</p>
<p>See the <a href="qtcharts-piechart-example.html">pie chart example</a> or <a href="qtcharts-donutchart-example.html">donut chart example</a> to learn how to use <a href="qpieseries.html">QPieSeries</a>.</p>
